Insulated steel wall panels polyurethane sandwich panels for workshops and hotel cold storage rooms
Polyurethane Sandwich Panel also called PU Sandwich Panel,the top & bottom sheet of this panel is Galvanized & Pre-painted steel sheets,and core material is 5 components Polyurethane glue, it is formed by heating, foaming & laminating. Polyurethane is the best material for heat and sound insulation. It can reduce the heat transmission caused by difference in the internal and external temperature, and get to maximum efficiency of freezing and refrigeration systems. It is a new type of heat insulation material for lower construction cost.Panels are in multiple varieties and specifications to meet the need of various sites and projects.

1. Energy-saving boards with good fireproof performance are A, B grade fireproof materials, which can effectively protect buildings and reduce fire losses
2. Good sound insulation/water tightness/air tightness Good sound insulation effect, effectively reducing 30 dB of external sound interference. Energy-saving board materials are hydrophobic materials, all joints between boards, airtightness-oriented design
3. Beautiful facade screw hidden node design, high board flatness, various board seam sizes, rich paint coating colors, and long-lasting colors
4. Thermal insulation performance Polyurethane thermal conductivity is between 0.019-0.023 w/m·k,
This is an excellent thermal insulation material. Node design with multiple functional requirements ensures sealing performance and thermal insulation effect
5. Strong and durable The stacking density is about 42 kg/m3;, 120 kg/m3;, 64 kg/m3;, and the three core materials are high in strength and durable
